Ontario Support Payment Calculator 2024
Calculate your child or spousal support payments according to Ontario’s latest guidelines. Get instant, accurate results with detailed breakdowns.
Introduction & Importance of Ontario Support Calculations
The Ontario Support Calculator is an essential tool for separating or divorcing couples to determine fair child and spousal support payments according to provincial guidelines. These calculations ensure financial stability for children and dependent spouses while maintaining fairness for the paying party.
Under the Family Law Act and Divorce Act, support payments are legally required in most separation cases. The calculator uses the Federal Child Support Guidelines and Ontario-specific tables to determine appropriate amounts.
Why Accurate Calculations Matter
- Legal Compliance: Courts use these same guidelines to determine orders
- Financial Planning: Helps both parties budget appropriately post-separation
- Child Welfare: Ensures children maintain similar standard of living
- Tax Implications: Support payments have different tax treatments

Formula & Methodology Behind the Calculator
Our calculator uses the official Ontario support guidelines with these key components:
1. Child Support Calculation
Based on the Ontario Child Support Guidelines, which use:
- Income Shares Model: Both parents’ incomes determine the table amount
- Provincial Tables: Ontario-specific amounts based on payor’s income and number of children
- Custody Adjustments:
- Sole custody: Full table amount
- Shared custody: Set-off calculation (40-60% time with each parent)
- Split custody: Separate calculations for each child
- Special Expenses: Added to base amount (Section 7 expenses)
| Payor’s Income Range | Monthly Amount | Annual Amount |
|---|---|---|
| $30,000 – $39,999 | $287 | $3,444 |
| $40,000 – $49,999 | $382 | $4,584 |
| $50,000 – $59,999 | $477 | $5,724 |
| $60,000 – $69,999 | $572 | $6,864 |
| $70,000 – $79,999 | $667 | $8,004 |
2. Spousal Support Calculation
Uses the Spousal Support Advisory Guidelines (SSAG) with two approaches:
- With Child Support (Primary Approach):
- Range: 40-46% of income difference
- Duration: 0.5-1 year per year of marriage (max 20 years)
- Without Child Support:
- Range: 37.5-50% of income difference
- Duration: 0.5-1 year per year of marriage
3. Combined Calculation Method
When calculating both child and spousal support:
- Calculate child support first using provincial tables
- Determine spousal support range using SSAG
- Apply “priority to child support” rule – child support is paid first
- Adjust spousal support if payor’s income is insufficient for both
- Consider tax implications (child support is tax-neutral, spousal support is taxable/deductible)
Real-World Examples & Case Studies
These practical examples demonstrate how the calculator works in different scenarios:
Case Study 1: Basic Child Support (Sole Custody)
- Scenario: Payor earns $85,000, recipient earns $45,000, 2 children, sole custody
- Calculation:
- Base table amount for $85k and 2 children: $1,102/month
- No special expenses
- No spousal support requested
- Result: $1,102 monthly child support ($13,224 annually)
Case Study 2: Shared Custody with Spousal Support
- Scenario: Payor earns $95,000, recipient earns $35,000, 1 child, shared custody (45/55 split), 12-year marriage
- Calculation:
- Child support table amount: $756 (adjusted for shared custody: $378)
- Spousal support range: $1,200-$1,500/month (40-46% of $60k difference)
- Mid-range spousal support: $1,350
- Total: $1,728/month
- Result: $1,728 monthly ($20,736 annually)
Case Study 3: High Income with Special Expenses
- Scenario: Payor earns $180,000, recipient earns $75,000, 3 children, sole custody, $12,000 annual special expenses
- Calculation:
- Base table amount capped at $150k: $2,106/month
- Additional for income over $150k: $300/month (discretionary)
- Special expenses: $1,000/month
- Total child support: $3,406/month
- Result: $3,406 monthly child support ($40,872 annually)

Interactive FAQ: Ontario Support Calculator
How often are the Ontario support guidelines updated?
The Federal Child Support Guidelines are reviewed every 4 years, with the last major update in 2017. Ontario-specific tables are updated annually to reflect economic changes. The most recent updates were implemented on November 22, 2023, with new tables effective January 1, 2024.
Key changes in 2024 include:
- 2.4% increase to table amounts to account for inflation
- Updated income thresholds (now up to $175,000)
- Revised shared custody calculation methods
You can view the official tables on the Ontario government website.
What income sources should be included in the calculation?
For accurate support calculations, include ALL income sources:
Primary Income Sources:
- Employment income (salary, wages, tips)
- Self-employment income (after reasonable expenses)
- Commissions and bonuses
- Overtime pay
Other Income to Include:
- Investment income (dividends, interest, capital gains)
- Rental income (after expenses)
- Pension income
- Workers’ compensation benefits
- Employment insurance benefits
- Disability benefits
- Spousal support received from previous relationships
What to Exclude:
- Child support received for other children
- Gifts and inheritances (unless regular/recurring)
- One-time windfalls (lottery winnings, etc.)
For self-employed individuals, courts may add back certain expenses like:
- Personal portions of vehicle expenses
- Home office deductions
- Excessive entertainment expenses
How is shared custody calculated differently?
Shared custody (where each parent has the child at least 40% of the time) uses a “set-off” calculation:
Step-by-Step Process:
- Calculate Table Amounts: Determine what each parent would pay if they had sole custody
- Determine Time Split: Calculate the percentage of time with each parent (must be at least 40% with each)
- Adjust for Time: Multiply each parent’s table amount by the other parent’s time percentage
- Set-Off: The parent owing more pays the difference between the two amounts
Example Calculation:
Parent A earns $80,000 (60% time), Parent B earns $50,000 (40% time), 1 child:
- Parent A’s table amount: $667
- Parent B’s table amount: $382
- Adjusted for time:
- Parent A owes: $667 × 40% = $267
- Parent B owes: $382 × 60% = $229
- Set-off: Parent A pays $267 – $229 = $38/month
Note: Shared custody calculations can become complex with:
- Unequal incomes
- Multiple children with different custody arrangements
- Significant special expenses
In these cases, consulting a family lawyer is recommended.
Can support payments be modified after they’re set?
Yes, support payments can be modified if there’s a material change in circumstances. Common reasons for modification include:
Valid Reasons for Change:
- Significant income change (usually 15% or more)
- Job loss or long-term unemployment
- Change in custody arrangements
- Child’s increased needs (medical, educational)
- Cost of living adjustments (annual inflation increases)
- Remarriage or new financial obligations
Process for Modification:
- Informal Agreement: Parents can agree to changes and file with the court
- Motion to Change: File Form 15 with the family court
- Mediation: Required in many Ontario courts before a hearing
- Court Hearing: Judge will review evidence and make ruling
Important Notes:
- Changes are not retroactive (only apply from date of request)
- You must continue paying the original amount until the change is approved
- Temporary changes (like short-term job loss) may not qualify
- Use our calculator to estimate what your new payment might be
For official information, see the Ontario government’s guide to changing orders.
What happens if support payments aren’t made?
Failure to pay court-ordered support has serious consequences in Ontario:
Enforcement Measures:
- Family Responsibility Office (FRO):
- Automatically enforces all Ontario support orders
- Can garnish wages, bank accounts, and tax refunds
- May suspend driver’s, professional, or recreational licenses
- Credit Impact: Unpaid support appears on credit reports
- Legal Consequences:
- Contempt of court charges
- Possible jail time for repeated non-payment
- Passport restrictions
- Interest: 1% per month (12% annually) on late payments
What to Do If You Can’t Pay:
- Contact FRO immediately at 1-800-267-7263
- Request a temporary reduction through the court
- Provide documentation of financial hardship
- Consider mediation to negotiate a temporary agreement
If You’re Not Receiving Payments:
- Register your order with FRO (automatic for court orders)
- Keep detailed records of missed payments
- File a motion for enforcement with the court
- Consider legal action for contempt of court

How are support payments treated for tax purposes?
The tax treatment differs significantly between child and spousal support:
| Aspect | Child Support | Spousal Support |

| Tax Deductible for Payor | ❌ No | ✅ Yes (if court-ordered or written agreement) |
| Taxable for Recipient | ❌ No | ✅ Yes |
| Reporting Requirements | None |
|
| Lump Sum Payments | ❌ Not allowed | ⚠️ Not tax-deductible |
| CRA Documentation | Not required | Must keep records for 6 years |
Important Tax Considerations:
- Spousal Support:
- Must be periodic (monthly) to be tax-deductible
- Lump sum payments are not deductible
- Payments must be made under a court order or written agreement
- Child Support:
- Completely tax-neutral since May 1997
- No deduction for payor, no income for recipient
- Special expenses portion may have different tax treatment
- CRA Audits:
- Keep all payment records (bank statements, receipts)
- Be prepared to prove payments were made
- Ensure agreements clearly specify tax treatment
For official tax information, see the CRA’s guide to spousal support payments.
What’s the difference between the Federal and Ontario guidelines?
While Ontario follows the Federal Child Support Guidelines, there are some provincial specifics:
| Aspect | Federal Guidelines | Ontario Specifics |
|---|---|---|
| Legal Authority | Divorce Act (federal) | Family Law Act (provincial) |
| Applies To | Divorced couples | All separated couples (married or common-law) |
| Income Threshold | $150,000 (federal tables) | $175,000 (Ontario tables) |
| Shared Custody | 40% time threshold | Same, but Ontario courts often use 45% as practical threshold |
| Enforcement | Varies by province | Handled by Family Responsibility Office (FRO) |
| Special Expenses | Section 7 of Federal Guidelines | Same, but Ontario courts often more strict on “extraordinary” definition |
| Updates | Every 4 years | Annual adjustments for inflation |
Key Ontario-Specific Rules:
- Higher Income Threshold: Ontario tables go up to $175k vs federal $150k
- Stricter Enforcement: FRO has strong collection powers
- Common-Law Inclusion: Ontario guidelines apply to common-law couples after 3 years (or 1 year with a child)
- Cost of Living Adjustments: Automatic annual increases unless agreed otherwise
- Retroactive Support: Ontario courts can order up to 3 years retroactive support
